Patented Apr. 25, 1933 UNITED STATES- PATENT OFFICE FREDERICK RIEBEL, JR., AND DEWEY DOW, OF TOLEDO, OHIO, ASSIGNOBS TO WAY ELECTRIC APPLIANCE CORPORATION, OF TOLEDO, OHIO, A. CORPORATION OI DELA- WARE VACUUM CLEANER Application filed May 20,

- The present invention relating as nominally indicated to vacuum cleaners, has more particular reference to a novel form of construction and assembly for dust collecting and air filtering bags to be used in combination therewith. The device embodying the principle ofour invention is more precisely adapted to be used with a type of suction cleaner which employs a removable sanitary porous paper filtering element.

An object of the present invention is to provide means for conveniently supporting the outer or fabric bag which serves to enclose a removable inner filter bag. A further object is to provide a construction whereby the outer fabric bag may be retained in position upon the vacuum cleaner, while the inner filtering element is removed or installed. It is a further object to provide means whereby the outer bag shall not be susceptible of misplacement upon the cleaner. Another object of the herein described construction is that the bag-supporting elements are readily removable from the bag itself in order to facilitate washing or dry cleaning thereof. Further objects and advantages of our invention shall become manifest as the description proceeds. To the accomplishment of the foregoing and related ends, said invention then, consists of the insane hereinafter fully described and particularly pointed out in the claims. r

The annexed drawings and the following description set forth in detail certain mechanism embodying the invention such disclosed means constituting, however, but one of various mechanical forms in which the principle of the invention may be used.

, In said annexed drawin s:

struction; Fig. 6 is a fragmentary enlarged sectional view of the upper amembly of the vacuum cleaner handle; Fig. 7 is an enlarged sectional view of the lower assembly of the vacuum cleaner;'Fig. 8 is a fragmentary enlarged side elevation, partly in section of the upper bag rod brackets and switch housing; Fig. 9 is an enlarged section taken substantially upon the line 99 of Fig. 6; Fig. 10 is a fragmentary cross sectional view of the spring mounted bag rod brackets; Fig. 1i. is an enlarged perspective view'of one of the removable bag rod clips; Fig. 12 is an enlarged fragmentary side elevational View showing the lower bag rod brackets; Fig. 13 is a fragmentary enlarged side elevational view of an alternative form of construction for the lower bag rod brackets; Fig. 14 is a section taken substantially upon line 14-14 of Fig. '13 Fig. 16 is an enlarged transverse sectional view taken through the vacuum cleaner handle and filter bag.

Referring more particularly toFig. 1, the general assembly of the vacuum cleaner is composed of the electric motor 1, a fan casing 52 with the air conducting tubes 3 and 4 attached thereto. A floor contacting tool 5 is mounted upon the end of the air conduit 4:. A rotary air valve and transparent dust indicating means 6 is adapted to direct the suction intake through the floor tool 5 or the fibre handle tube 3 at the will of the operator. A fan easing outlet indicated generally at 7 din cts the dust and dirt laden air into the interior of the bag 8.

Directing attention to Fig. 7, the outer bag 8, which is composed of cloth or similar material encloses a suitable porous paper filtering element '10. A cone-shaped coupling or adapter 11 is secured to the mouth of the inner paper filter bag 10 by means of the tapered sleeve 12 which is clamped in position on the coupling 11 by means of the threaded ring 13. T e fan casing outlet 7 has the flanged conical seat 14 to receive the outer end of the coupling 11. A ball and socket detent 15 is suitably ositioned in the outlet 7 in order to removab y engage with the complementany groove in the coupling 11. There is also the additional coupling securing means consisting of knurled thumb screw 16, which may be employed to maintain a more secure attachment of the cou ling 11 to the outlet 7. As best shown in ig. 15, the uppermost 5 edge of the outer filter bag 8 is in the form of an openable mouth comprising the marginal sides 20 and 21 with a closing flap 22 positioned therebetween. A pair of hollow metallic rods or tubes 23 and 24 are enclosed within the upper edges of the sides 20 and 21 respectively, and extend the entire length of the outer bag 8.

As most clearly illustrated in Figs. 6, 8 and 11, a resilient metallic clip 25 is designed the si s 20 and 21 of the bag 8. The metallic clip 25 has the resilient prongs 26 which are adapted to removably clamp over the fabric of the bag, as well as the transverse projecting portion 27 with the hole 28 drilled therein. The hole 28 is adapted to register with the tapped ends of the hollow rods 23 and 24. Projecting stud pieces 30 and 31 are then threadably secured to the ends of the bag rods 23 -and 24.

By reference to Figs. 8 and 12, which are drawn on the same scale, it will be seen that the diameter of the projecting studs 30 is greater than that of the studs 31. The purpose of the latter type of construction 1s to insure against misplacement of the filter bag 8 in relation to the vacuum cleaner. The supporting devices for the bag rods which are to be presently described, likewise possess such a difl'erential diameter construction. It will thus be seen that it is possible to secure the bag 8 in proper position only, otherwise the projecting studs 30 and 31 will fail to re ister with their respective supports.

ferring to Figs. 3 and 5, the lower bag rod brackets 34 for reception of the studs 31 have the transversely positioned holes or recesses 32 and 33 and are screwed or otherwise fastened to the top side fan of the casing outlet 7. The bracket 34 also carries the lower electric cordhook 35.

Directin attention to Figs. 4, 8, 9 and 10, the upper ag rod latch members 36 and 37 which receive the studs 30, are slidably mounted in the housing 38 which is in turn fastened to the electric switch assembly 9. The switch assembly 9' is composed essentially of the electric toggle switch indicated generally at 39 with the integral annular ring 40 which is adapted to slip over the hollow fibre handle tubes 3' and The switch assembly also includes the insulated knurled ring 41 which is adapted to reciprocably operate the toggle switch 39. The spring cord guard 42 and the upper cord hook 43 are also attached to the switch housing 9. All of the last described component elements constitute -a compact and readily installed assembl The slidably mounted upper bag rod atch members 36 and 37 extend through the to be (positioned upon the outer corners of spring housing 38 and have the downwardly and transversel pro'ecting triggers 45 and 46 respective y. rings 47 and 48 attached to the lugs 49 an 50 serve totensionally maintain the latch members 36 and 37 in securing attachment with the bag rod studs 30.

An alternative form of construction for the lower bag rod brackets is illustrated in Figs. 13 and 14. The hollow fibre tube 3 is secured within themetallic casting 54 which has the projecting ferrule 55 which in turn is adapted to be clamped in the s lit collar 53. As best shown in Fig. 14, t e casting 54 carries the downwardly extending bosses 56 and 57 which have the recesses 58 and 59 respectively. Such recesses 58 and 59 are adapted to serve as a substitute for the lower bag rod brackets 32 and 33.

It will thus be seen that we have provided a type of construction for a vacuum cleaner be support which may be readily removed and installed in position, and correct position only, upon the vacuum cleaner. Furthermore, as illustrated by the dotted lines in Fig. 15, at the mouth of the bag may be opened and the inner filter element replaced or removed while the bag retains its position on the cleaner.

Other modes of applying the principle of our invention may be employed instead of the one explained, change being made as regards the mechanism herein disclosed, provided the means stated by any of the following claims or the e uivalent of such stated means he emgoy e therefore particularly point out and distinctly claim as our invention.
